How to Convert JPG to AVIF Online

JPG to AVIF: before and after JPG A JPG FILE JPG TO AVIF AVIF A AVIF FILE

This converts a JPG photo into an AVIF file, the format that gives the smallest images on a modern website. You drop in the JPG, set a quality slider, and download the AVIF with its size shown next to the original. AVIF is usually about half the size of a JPG that looks the same, which is why site owners and theme builders use it.

Converts JPEG to AVIF, which is typically 50% smaller at the same visual quality. The trade-offs are encoding speed, which is slow, and support outside browsers, which remains patchy — excellent for a website, awkward for a file you are sending to someone.

Tips and Good to Know

  1. Encoding AVIF is slow, so a large batch of full-size photos takes a while. Convert a few at a time, or use JPG to WebP if speed matters more than the last few kilobytes.

  2. Not for a file you are sending to someone. Older phones, some desktop programs and many email clients still cannot open AVIF, so keep the JPG for sharing.

  3. Do not run a photo through it twice. AVIF is lossy, and each generation loses a little more; keep the original JPG and convert from that.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to convert JPG to AVIF?

No. JPG to AVIF runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to convert JPG to AVIF online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

Does JPG to AVIF reduce my photo’s quality?

Converting and cropping keep quality close to the original. Compressing trades a little detail for a much smaller file, and a lighter setting keeps more of it. Compare the preview with your original before saving.

Will my photo be accepted by the exam form?

The exam photo tools follow the size, dimensions and file weight given in the official notice. Always read the latest notice too, because boards sometimes change their rules between years.

Can I edit pictures with JPG to AVIF straight from my gallery?

Yes. Pick a photo from your gallery or take one with the camera, then save the result back to your phone. Everything works in the browser, so there is no app to install.

Is JPG to AVIF free with no watermark?

Yes. Use it for as many pictures as you need without an account, and each image comes back without any logo or mark from the site.
